BEAMFORMING TECHNIQUES USING RANDOM-BASED PARAMETER SELECTION AT RECONFIGURABLE INTELLIGENT SURFACES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240162939 titled 'BEAMFORMING TECHNIQUES USING RANDOM-BASED PARAMETER SELECTION AT RECONFIGURABLE INTELLIGENT SURFACES

Simplified Explanation

The abstract describes methods, systems, and devices for wireless communications using a reconfigurable intelligent surface (RIS) to transmit reference signals to a receiver. The RIS adjusts parameters for its elements to provide different beamformed parameters for reflected instances of each reference signal, based on channel measurements by the receiver. The transmitting device communicates with the receiver via the RIS using the selected reference signal.

Original Abstract Submitted

methods, systems, and devices for wireless communications are described in which a transmitting device may transmit a set of reference signals to a receiver via a configurable surface such as a reconfigurable intelligent surface (ris). the ris may randomly adjust one or more parameters for one or multiple ris elements to provide different beamformed parameters for reflected instances of each reference signal from the ris. each reference signal may have a corresponding reference signal index value, and the receiver may provide an indication of a selected the reference signal index value based on channel measurements of the reference signals. the transmitting device may provide an indication to the ris of the index value, and may communicate with the receiver based on the selected reference signal via the ris, where the ris uses the parameters associated with the ris index value for the communications.
